Actually it's not the best LBSC design. Beginners think it's a good first engine when in fact it's complicated with tiny parts and poor results unless well made. The original small boiler version looks the best and goes well if constructed to a good standard. Even LBSC had his doubts and upgraded to the larger boiler. Juliet is a better first engine or even a small 5in tank.
Thank you, the scale is 31/2 inches, haven,t done any video,s for a while as windows stopped thier version of movie maker, and just haven,t had the time to learn a new one but will make an extra effort to sort this out.
As a model engineer of over 70 years and 6 passenger hauling locos built (including a Tich). If you are new to the hobby and not an experienced engineer I would suggest you do not build a Tich. There are as many parts as a little larger engine such as a Juliet or even a small 5in. If you want your Titch as an ornament go for the small boiler one. To drive then the large boiler but the loco has very little extra capacity and therefore has to be well engineered. There are far more uncompleted ones than completed examples😕
The rear axle and wheels are locked from side to side movement by the two slip eccentrics but what locks the front axle and wheels from moving from side to side I am currently building a titch and dont know whether side to side movement in the front axle will lead to the connecting rod hitting the piston arm.
