If you buy from them on a regular basis, as part of your ordering process, you will have been offered the opportunity to have your details added to their mailing list.
If you have declined this offer, the only way they can contact you is by unsolicited commercial email (more commonly known as spam). Arc do not engage in this underhand practice. You cannot criticise them for respecting the privacy you yourself have requested.

PowerSports / Ebike trike conversion
« Last post by BillTodd on September 26, 2025, 07:29:20 AM »Probably just another fantasy cad project, but inspired by YouTube videos here's my idea for converting my Kalkhoff (https://www.madmodder.net/index.php/topic,13896.msg165815.html#msg165815 ) ebike to a tadpole leaning trike.
The idea is to attach the trike chassis to the top motor mount and forks . I may have to add bracing to the fork or bracing up to the head-stock to take the extra leverage of the cargo section.
It has to lean for stability as I can only make it about 650mm wide .
The hope is it'll do the green waste disposal job I currently use my vastly more expensive R&M for ...

The Design Shop / Re: Surface grinder concept/project
« Last post by BillTodd on September 26, 2025, 06:59:09 AM »Another rethink about the base design.
Instead of having to cut a 10" wide slab on aluminum down to 5" . I think I'll keep it 10" deep and fill in the the front and side with thinner plates and use another 1" thick piece at the back
If I cover the front left side with the extruded T-slot I have, it might be useful for mounting a rotary table for cylindrical grinding

« Last post by BillTodd on September 26, 2025, 06:38:29 AM »Here's a couple of pics of the prototype extruder module.
the clip on the left side ejects the extruder when released and then holds it in place until manually removed.
I'm using clone bambu hotends .

This is a dual switching extruder idea I've been working on for the Frogspawn
The basic function is that the separate hot-end / pinch roller assembly pivot to an angle , disconnecting the pinch drive and slightly lifting to one-side the nozzle.
a spring latch releases one extruder assembly when the other is pushed into the latch . Selection of either extruder is by simply pushing the print-head into a sprung lever on the far right front.
I've added a bed-probe that will be dropped when homed by releasing both extruders.
The extruders can be removed from the print head with a clip that should allow an alternative extruder to be swapped in easily .
I have prototyped the print-head and switch mechanism and i'm finalising the design of the coolers

I have about a dozen or so Hit & Miss engines (my plan of course was to only ever have one!!!)
But this is absolutely at the top of the pile an instant favourite!!!
Let the mods begin!!!

A buyer for the existing business has not been successful, so all the stock is either sold or being sold at reduced price.
At least the business has not become a victim due to our govt pressures.
