My Picco has issues staying running without the glow plug igniter. I got this in an ebay lot about a year ago. The guy said it was new and it looks new. The. The pinch is crazy tight. I'm going to run a couple of half tank heat cycles through it first.

Have had this Shark vacuum very long and the from roller belt rubbed a hole through the side plastic. I could find the replacement part so I decided to find a solution. Cutting out a small piece of medal solved the issue. The metal will prevent the belt from coming out in the future. The friction of the belt melted a hole though the plastic. https://www.amazon.com/gp/product/B08VDV4DC8/ref=as_li_tl?ie=UTF8&tag=fintechcomm0f-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B08VDV4DC8&linkId=4fc07f45cd4abcbb76fad81bd3b4e7e6

I picked up this Picco nitro engine on offer up for $200. Picco .28 engines are hard to find. This one looks pretty new. The guy said he ran a couple of break in tanks and that was it. I decided to put in some ceramic bearing to give it a little more top end. I don't have me driving on Camera but this thing is insanely powerful.

I got this from a customer that attempted to install a BLtouch. He originally had a 4.2.2 board. Its was worth $35 to upgrade to the newer silent board with trinamic drivers. This unity also had the creality 5 pin connector BLtouch. I'm actually surprised how well this prints with creality's stock firmware.

I picked this massive printer from a customer. The Bed is 500mm x 500mm. The printer sat for 2 years. I converted the mainboard to a newer Marlin 2.0 32bit board. The cool thing about the SKR Mini E3 board is that its a direct replacement for Creality. The customer also gave me a Creality Branded BLtouch with 5 pin connector.

A customer dropped this off for repair. He did some very nice upgrades but somewhere along the way the firmware had a problem. I'm suspecting he loaded the wrong Marlin firmware for his board. The board are very specific. You need the right pinouts in Marlin or all hell will break loose. I'm guessing the pinouts where wrong for that LCD. The Creality V2 screen is not a real screen that interfaces with Marlin. Its more like a mini computer sending gcode.

I found this engine on eBay for $160. This is by far the best engine I've seen so far. DLC coated crank and ceramic bearings. The engine is a 7 port high revving engine.

I've been messing with my two Gigbyte RTX 3070. I wish I could buy more but the scalpers are ridiculous. I paid a scalped $750 for standard card and $800 for the Aorus. Now those same cards are going for $1400-$1500. The trick to have the power low enough to keep the card stable. If the power is too low the GPU will not start or a rise in ambient temp could crash the card.

My T-maxx 1.5 clone would not shift into second gear. I decieded to tear and it down and figure out how it works. Its actually a pretty cheap lazy design. On higher end RC cars you will have a clutch that smoothly transitions into second gear. On the Traxxas design it immediately blows into second gear with no smooth transition. This transmission had gease in it. Nylon or plastic gears do not need grease. Only grease metal gears.

I'm ready to install my freshend up HPI Nitro star 3.0 engine. When I pulled the old exhaust off I noticed the exhaust outlet was tiny. This would have created back pressure chocking off fresh air from coming into the carburetors. If you want to try powder coating look the machine below. Its pretty easy. You should also get a sandblast cabinet. You will also need an air compressor.

I've been rebuilding RC nitro engines and come across a lot of old rubber seals. Replacing these rubber seals would cost as much as the engine if I could find them. I've been using this method for years. I use silicon spray and let it sit for about a week in a zip lock bag. Most rubber is not natural anymore and made from petroleum. If you need faster results use WD40 or PBblaster. Any heavy petroleum distillate should work. Sometimes the heavier stuff can weaken the rubber.

I picked this engine up for $25 on offer up. The compression feels good. I had to get a few carb parts to make it work. I couldn't get the cooling head clean so I decided to anodize it again.

I got this Associated Electronics in a eBay nitro engine lot. I'm guessing about 10-15 years old from research. The carb that was on it had a downward curb idle screw. I changed to a better plastic carburetor. The plastic carbs don't suck as much from the engine. Cooler gas equals denser charge.
