I grabbed the tb from a fire damaged van. So the anodizing on the body badly affected and all the meltables gone. That’s the tps and the bearing seals and additional shaft seals.

But the body was good. I blasted it, popped in new bearings, and thought I’d try to make an off the shelf, meaning my shelf, micro switch work as a tps sub.

Oh and I also had to make a cam for the switch , goes on the throttle shaft.

Oh yeah, of course, I made a delrin cover .

This was all just for the exercise. I haven’t tried it out .

I’m testing this device. It’s the one on the right . The left hand AFM is what I’ve been using . Chinese made replacement board .

Only been a few days but has worked flawlessly . It replaces the carbon track board and the wiper with an optical sensor set up . More to come but I’ll say now it’s working perfectly. Smooth throttle response, prefect throttle tip in, no bucking on slow trailing throttle crawling .

It got too cold for the aluminum shift knob I made a while back. I mean it, it’s not the greatest choice of material for a shift knob. So yesterday afternoon at end of work I quickly made one with a bit of wood. Scrap teak that I had at work for some reason. Could have been bigger in diameter but that’s what I had. Wood screwed onto a threaded boss in the aluminum base.

The new semi wood

That thing I posted a while back, more stuff on it. Bag has the pump and shower head ( https://www.flextail.com/en-ca/products/max-shower).

Shower was Xmas gift from good friends Simon and Maria. Works very well testing it at home .

I went down this silly rabbit hole about a month ago. I thought it would be easy to make a pair of door latch surrounds. Well it wasn’t , made mistake after mistake. Finally got something that works, but it sure wasn’t worth the effort.

Yes, there are aftermarket aluminum versions. I think it’s uniwerks that sells some UK made units. That set includes the trigger and the trigger mount. I chose to try and use the stock trigger and mount, and that was a huge part of my problem.

Pics show some of my attempts, including 3d prints. And my final attempt, the “good enough, I’m not gonna waste any more time” , powder coated and on the door.

Started fooling with this about 4 years ago then I lost interest. Was more of a design exercise than anything else. I had this notion of a spacer set up, keyed to the handle…. Blah blah…

I don’t have a broach to cut the internal splines so I did a kludge by drilling small holes then boring a boring with a slight taper. Seems to work, but I haven’t used handles much.

The knobs are delrin, and a bearing pressed and glued into handle. That part of the experiment works well.

I think I’ll revisit this project soon and do a bent handle for more clearance. I’ll keep the delrin knob as I like that better than the knurled knob on the GW handles ( been using them for a year, I find the knurled knob kinda not great).

Another thing I’ve been playing with. And I’ve posted about them but they deserve their own post .

Machined aluminum handles for front door. Yeah, there are some for sale on the market still, I think. Syncrotimes https://www.syncrotimes.com/

They do an anodized version for a crazy low price. Check them out.

Anyway, back to me .

I’m not a fan of “billet” aluminum things. Maybe it’s because I’m matching aluminum all day and I really don’t want to see it all the time 🙂

Plus they are cold, or hot depending on the weather, to the touch.

But I made these. Solid and ones with holes. And once they are powder coated, by golly I like them. Don’t seem as cold once painted.

It’s a two set up operation for machining as you can see in the pics.. Then I tumbled them, and painted some. I left a pair of the solid versions unpainted , polished the tumbled finish and wondering if I should try a partial leather wrap .

Notice I’m only using the two large screws that go into the plastic insert in the door. The smaller screws are not needed.

I posted about them a few weeks ago but decided to post again by themselves .

Something I’ve been working on , on and off since summer. I’ve tried out various styles but I like the rectangular recessed ones best.

They are 1/4” 5052 aluminum, machined, bent, then powder coated. Held onto the stock pedal ( after the plastic stock pads are removed) by cross bars top and bottom, m4 socket headed cap screws. The bars go behind the pedal.

I’ve had a pair of non painted, raw aluminum ones on van since summer. There’s no problem with a wet foot slipping off pedal .

Pics show a sample of the designs I tried, the ones in the van, and the powder coated ones I’m going with.

Yes I’m going to make a few to sell.

Ok, right away, I know this will appeal to only a few. But it works well, it’s stiff and secure. I quickly machined a bear spray holder and printed a flashlight holder for examples of things to attach. Bag type things can use Velcro straps. Yes, it’s the molle/PALS type system.

I’ll make them to sell if I get enough interest

Revised my thinking on an oil tower. I posted about original plan a few weeks ago. But now I’m not putting putting on a golf mkii “pcv” thing on top of my aluminum tower (Teflon baffles inside ) i took one apart and in all respects except for the diaphragm size, it’s identical to the van set up.

I’m doing this one free flow thru. I’ll see how it goes.

Hose barb Part just a tight press fit. Cap screws on , Teflon washer to seal.

If you want to read thru my understanding of the stock tower… here you go

The main body of the tower has a removable baffle . Above that you can see a right angled bent tube. This tube has a small hole in it facing down, towards the engine. This tube continues out thru the tower and is what connects to the engine air intake upstream of the throttle body via rubber hose. Also in that path is a heating element , with a narrow orifice, maybe 5mm diameter. Heating element to prevent icing , the narrow orifice presumably to restrict air flow to a degree.

Back at the tower, inside, where the tube curves 90 degrees up ( and again, mention of the small hole on the underside of that bend) the tube ends and there is a rather weak spring supporting a rubber diaphragm. The spring keeps the diaphragm off the end of that tube. In other words, the passage from the crankcase to the intake boot is clear. The diaphragm is attached to the tower top, with some space above it. There is a small hole on the underside of the top of the tower that connects to the space above the diaphragm, thus keeping that space at atmospheric pressure.

So when does that diaphragm do anything? Well… as far as I can tell the diaphragm is pulled down to block the bent tube leading out of the tower when you have greater than a certain amount of intake vacuum. Probably not at idle or at wide open throttle . More likely at some mid throttle range.

Btw, the pro training manual has description of the tower and function but I’m not sure about the statements made there of when there is high or low intake manifold vacuum.

That little hole at the bend of the tube inside.. I’m guess that allows some passage from crankcase even when diaphragm pulled down under high intake vacuum.

In short, my understanding is… the crankcase vapours are allowed to travel up thru the tower and then into the intake manifold when there is not sufficient intake manifold vacuum to overcome the spring pressure and pull the diaphragm down. When there is sufficient vacuum then the diaphragm is pulled down and the passage is closed saved for the little bleed hole .

Update December 2023. Been running it since I posted this. Seems to work fine, can’t detect any engine running differences. I had a look inside it after a couple of weeks, nothing much to report. Oh one thing, you see how I used a Teflon gasket instead of an oring. Was slightly worried that joint would weep oil. But it hasn’t. I’ll add those pics to the gallery. I’ll prob look inside again over the Xmas break.

Just fooling with an idea. The 90’s era Vw pcv valve shown here is a place holder of sorts.

Tower packed with Teflon. Screw top in case needs cleaning without taking tower off engine block. I’ll try it out in a bit, going on holiday next week , exploring Klanawa again

Last weekend one of them let go under pressure testing. I was trying to find leak at tee. Yes I did catch a whack of coolant on my face.

Van cafe and others sell metal replacements. That’s the smart way to go. I didn’t go that way.

Made a pair from 6061, 3/4” thick stock. Also bought 15’ of gates heater hose to replace the runs from tees to rear heater.

I was trying to cut and etch leather with diode laser. Had to have something to use as test. Made a key fob thing with a message .

Yeah I haven’t dialled in the settings.

Recently had a go at making aluminum fuel rails to replace the stock plastic ones. I wasn’t really taken with the current choice on the market. I thought they were a bit big. So I slimmed down. Been running a pair on my van for last couple months, and have some others out for testing and critique.

Had some powder coated black and some anodized grey .

Yeah that’s an aluminum copy of the stock shift knob.

Starting to install one of those remote switch to solid state relay box type set ups. Just got the mounting plate done so far. Aluminum and slight texture powder coat. Not sure what will be controlled by this. You get stickers to go on the switch pads. I’ll show when done.

I’ll show finished later . Later has arrived…

It’s another version of the socket part of the ball and socket linkage back at the transmission. Other versions I made a while back here .

The idea of the spiral grooves is to retain some grease … that’s a tumbled finish on the part, gonna paint it. Bore hasn’t been deburred in this pic. The end has a rim to help keep the boot on.

M6 bolt goes up through the shift rod.

End of day today made another, slight changes. Any excuse to use this lathe .

Not finished, but you get idea. More thickness at bottom and a more sexy ridge at top for boot .

There is one thing I haven’t said.. one more step. I’ll show when done.

And done. I’ve done away with the roll pin years ago. The split clamp and bolt better, especially as the shift rod probably worn and the roll pin hole wallowed.
