Hi all, I've been manufacturing parts mostly to assist with my own resto projects. Just a heads up that once the current stock sells I don't intend to make any more (due to family commitments etc) so the parts won't be available for much longer. Here's an update of stock: Gearbox plate - 21 left, https://www.ebay.co.uk/itm/225130030935 Custom diff - only 11 left https://www.ebay.co.uk/itm/225546378902 - these things work incredibly well! (It's the only part I'd be tempted to re-release) A1 Bracket, screw version - 32 left https://www.ebay.co.uk/itm/225270660602 A1 Bracket, pin version - 21 left https://www.ebay.co.uk/itm/225230838638 A2 Diff cover - 16 left https://www.ebay.co.uk/itm/225457587196 Alloy diff housings - 33 pairs left https://www.ebay.co.uk/itm/225444424246 Just a heads up to forum members to grab any whilst you can. I still have the computer drawings of all designed parts so these won't be lost, but I don't intend to restock anything, aside from being tempted by a v2.0 of the planetary diff. Hope it's useful!

Any volunteers to test some 3d prints of this part? I don't own an egress (very sadly) If so please DM me and I'll ship some out

Would have been simple enough but it's good that they're available on shapeways. It'd be nice to find a professional machinist in the community as it'd drop the price of everything. After designing parts they have to be machined to a +-0.02mm tolerance or the quality is poor. Sadly it's expensive unless a bulk order is made, but there isn't enough demand to order in bulk. If I had time I'd create a community site where members can request parts to be designed, then the cost of machining can be split

Interesting info thanks, it looks like the front towers are the bigger problem, it's a much bigger task to design some of these but not out of the question

Hi all, I was asked to look into producing an alloy rear shock tower for the egress as I believe they break on impact?! So this is what I've come up with: I'm, assuming there's a need for this part? Anybody have any design considerations I may have missed? I've replicated the originals but it's a chance to improve it. I don't own an Egress so I'm unaware of anything that relates to this shock tower. Thoughts and feedback appreciated - Thanks

3D print sorted and looking good. I'm making an assumption that these gears are in short supply also, so I'll get the initial all acetal version machined then look into the steel version:

idle gear CAD files/drawings are done, first off there's a match to the original but machined in Acetal which would be stronger.. Then there's an extra strength design which would have a detachment in steel, the plastic part being Acetal again: These would have to be joined with a relevant epoxy. As with the Diff these are a perfect .80 module and stronger than the originals. The metal one is similar to the thorp gears that were available but I've attempted to improve the design as the thorp gears had two of the teeth extended which would upset the balance of the gear. This one has been designed to have the same balance

It's doable, but I'd need to know if the drive cups would work with the king cab, and if the internals for that diff are readily available. I'd be interested to know if there are models outside of the madcap/king cab that require parts also as it would be nice to produce some parts for other popular models where there's a need

My experience with testing was similar as far as AW grease goes although I've not tried the oil. So far the molybdenum grease works its own way to the gear shafts nicely and runs well in the diff, would be interested to try a few other types though

I think the geared diff is working as it ought with molybdenum grease (thanks @Champ85), as it's not based on a modern oil filled sealed design. They're a whole other level with bevelled gears. It's certainly running extremely well when used with a brushless which is nice - I believe some people completely lock their diffs intentionally, although I couldn't comment as to why. Doesn't sound like a good idea to me although they probably know more than I do

Great news! One thing I've noticed since adding new parts to these vintage vehicles is just how much performance degredation there has been over the years/decades. Sometimes it's almost unnoticed too until a new part turns it into a new vehicle and it's brought back to life. It's great to see people doing such a good job of getting these back on the road. Excellent work

Someone with more RC experience can comment on this but I find the geared diff to be extremely smooth and very consistent. There's a constant spin in opposite directions of the wheels which is never interrupted. Seems a lot better than a ball diff to me personally as I've found that ball diffs on the vintage vehicles works well, but isn't this consistent:

does anybody know what lid screws are included with the Tamiya diff? ... https://www.ebay.co.uk/itm/295271869767 As I've tried these and they're much better than the larger ones I used ...edit the answer is Tamiya 9804477/19804477

All sorted. Delighted with these, with the SA version you can easily flex the plastic, these are a lot more solid -The acetal is very strong, if anybody is looking to get their diff upgraded just send me a message. At some point in future I'll work on other elements of the transmission but it's going to be a while, I'll have a busy year with twins on the way soon.

I need to delay release of these to make a tweak. Will keep you posted....
